FIRE PLUG.

APPLICATION HLED MAR. 30; .917.

ATTORNEY EARL STROMINGER, OF STOCKTON, CALIFORNIA.

FIRE-PLUG.

Application filed March 30, 1917. Serial No. 158,688.

and State of California. have invented certain new and useful Improvements in Fire- Plugs, of which the following is a specification.

My invention has reference to hydrants or city fire plugs and has for its purpose the provision of a the plug which may be disposed beneath the surface of the city pavement in such a manner as to be concealed from view, while at the same time, being readily accessible in case of emergency. By such arrangement..I propose to assist in the beautifying ot' a locality by removing from its thorough-fares all unsightly obstructions or obstacles such as the projecting type of fire plug hydrant so common to the larger cities and which are supported externally of the pavements thereof.

A further object is to provide a hydrant of the character described which has provided thereon a plurality of separate and independent hose-comiections, each having a separate valve mechanism and capable of being used without int rfering with the use of the other connectioiih.

A still further object of the invention is to provide a fire plug which has a number of out-let cylinders. capable of being separately connected to a plurality of hose lengths, thus providing a source of water supply for several fire engines at the same time.

With these objects in view, the invention consists in the novel construction and arrangement of parts, as will be hereinafter described and claimed, reference being had to the accompanying drawings in which:

Figure 1 is a sectional view taken'through the sunken inclosure and illustrating the position of the fire plug therein, and

Fig. 2 is a top plan view, illustrating the curvature of the water chest, the position of the outlet cylinders or plugs, and also the rectangular casing which may be employed for housing the parts of the device below the level of the ground. as represented in Fig. 1.

Referring more specifically to the drawings, 1 and 9 represents sections of an underground watei supply pipe or main through which a city receives its water supply. At

a suitable place the soil is removed from Specification of Letters Patent. Patented Dec. 10, 191 8..

about the main. so as to provide a recess 3 which has its open end substantially level with the sidewalk or road 4, as the case may be. In depth. this recess should extend beneath the sections 1 and 2 a sutticient dis tance to permit the water chest 5 to be connected to and to unite' the sections 1 and 2 of the water main. As will be noted, this water chest has the flanged portions 6 into which the opposed endot' the sections 1 and '2 ar adapted to be securely received and provides a c ntinuous passage way or conduit for the water.

The center portion 7 of the main is positioned out of the direct path of the Water as it is discharged into the end of the Water chest, as -will be clearly understood from Fig. 2, in which the arcnate or curved formation of the water chest is clearly shown. The. water as it enters the chest from either of the sections 1 and 2 will-then be caused to swerve in its direction as it passes through the chest, being momentarily halted before its passage into the opposite section of the main. Asthe discharge or out-let cylinders are positioneu directly above thearcuate base portion of the water chest, the suction exerted theretln'ough, by means of the first engine or other pump attached thereto. will take immediate advantage of the momentary check n the flow of water through the water chest so that t '\\'ill be drawn in full cuantities through such of the out-let cylinders as may be in use, without effecting, to any.

material extent, theordinary How of water in its usual passage through the water main.

The upper portion of the water chest extends upwardly in a restricted curve to provide a neck portion 8 into which the water is adapted to accumulate and to be fed through the cylinders or plugs 9. Each of the plugs 9 extend substantially in a vertical direction from the neck portion 8 of the water chest and have their lower ends 10 issuing into chamber and compartment 11 which is common to all of them. The upper flanged ends 12 of the plugs are positioned to terminate beneath the open end 2 of the recess 3 but lying in proximity thereto 'so that connections may be readily made to each plug. Suitable valve mechanism 13 is provided upon each of the plugs and may be operated to openor close the plug independently of the other cylinders.

IOU

material adapted to protect and preserve the working parts of my invention in good wori'zing condition may be employed. This acie i-i is inserted in the sunken re and, is of course. provided with the .ry openings to permit the ends 1 and E2 01 the water main to pass therethrough in a manner previouely descrihed. Over the open. end of the recess of sunken receptacle l iarranged a suitahle cover 15' which is adapted to iie flush with the surface of the ggjrtuuul or pavement and which conceals the tire plug troin view. v

in use. the hydrant is ver v *aaily and tptici'ciy brought in operation. it merely heijng nece'eaar v to remove the cover l'iHilllS 15 which is to he so positioned as to he eapahie oil" being I'OlllOVttl in an instant so as to permit of ready access to the plug 1). After making); the proper connection to as many of the plugs ah ma he. thought ad'- isabie. the valve wheel 16 of each plug may he promptlvadjusted so as to open the valve and permit. the water to he drawn from the niutuai Supp-if," chamher 11 into those plugs being: ur-seti. it dcairethsuitable parkiugiuav he arranged within the receptacle to aurround and. keep the lower parts of the de-- vice in comtant workingcondition and to prote t it to :auue extent against inoperativenerss' caused in 't'reezing. etc

Although the above description refers to what might. he considered the preterred embodiment of the invention. it: is to he cleariv 'uinlerstood that certain (ilttttfl'tH in the (id tails construction. arrangement. and proportioinnmit. of parts may he resorted to within. the acope at;v the appended claims.

without sacrificing any of the advantages thereof.

What 1 claim aa new and desire to secure by Letters Patent is:

1. in a lt}."(il'itnt, the combination with a receptacle disposed within a recess and having openings formed in certain of the opposite waiie thereof. of: main-pipe sections projecting through said opei'iinga, a water chestin said reccptaeie disposed to he in the path of said mainpipe and connected thereto Said water chest. being; oi? arcuate formation so ac to halt the passageof water teniporarily a plurality of posed out-let cylinders arranged on said. water chest. aaid cylinders having their lower extremities; united to provide a reeervoir common to all oi the cviindera and having their upper out iet ends suhjacent to the, opened end of the 'rccesa', and remo abie means for covering" said recess and receptacie. 1

2. In a hydrant. the combination with av receptacle disposed within a recess andi'ntving openings termed in certain of the opposite wails thereof. main. pipe Sections projecting through said openings a water chest in said receptacle disposed to. he in the path of said main pipe sections and connected thereto. said water chest being or arcuate 'iormation so as to halt the passage of water het'ore it enters the. other section of the main pipe. nd a piuraiit of valve regulated evlinders or plugs extending in a 'erticai. position 't'rom the water chest.
